Here are the materials in Oneida Tribe of Indians of Wisconsin v. Village of Hobart:
An excerpt from Judge Posner’s opinion:
Nevertheless we can imagine an argument, built on our earlier example of the Village’s authority to deploy its firefighters on Indian parcels, for an exception of necessity—a common law graft onto the Clean Water Act—to the Oneida tribe’s exclusive authority over Indian land. But the Village doesn’t argue for such an exception; it doesn’t deny the feasibility of cooperative arrangements between it and the tribe, which has signed cooperative service agreements with other government bodies in the area.
So Hobart loses its case against the tribe. And there is another reason it must lose. Because federal law forbids states and local authorities to tax Indian lands, the tribe can’t be forced to pay the assessment decreed by the challenged ordinance if the assessment is a tax.
